T45.8X3Poisoning by other primarily systemic and hematological agents, assault

T45.8X3 is the ICD-10-CM diagnosis code for poisoning by other primarily systemic and hematological agents, assault. It belongs to category T45 (poisoning by, adverse effect of and underdosing of primarily systemic and hematological agents, not elsewhere classified), block T36-T50 (poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T45.8X, choose T45.8X3 (Poisoning by other primarily systemic and hematological agents, assault) only when documentation doesn't support a more specific option: poisoning by other primarily systemic and hematological agents, accidental (unintentional) (T45.8X1), poisoning by other primarily systemic and hematological agents, intentional self-harm (T45.8X2), poisoning by other primarily systemic and hematological agents, undetermined (T45.8X4), adverse effect of other primarily systemic and hematological agents (T45.8X5) and underdosing of other primarily systemic and hematological agents (T45.8X6).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
